I had ulcerative colitis from I was 18 until 46 which is a chronic inflammation with blood in the faeces. I switched to the carnivore diet and within some months all my symptoms disappeared. This was also confirmed with a colonoscopy in a hospital. My brain fog is also gone.

I used to be really strict but now I am more like 90-95% carnivore, but I try to get the carbs from potatoes, carrots and Nuts. I aim for under 50-100 grams on carbs a day since I lifts weights and do some CrossFit.

Info: Ulcerative colitis (UL-sur-uh-tiv koe-LIE-tis) is an inflammatory bowel disease (IBD) that causes inflammation and ulcers (sores) in your digestive tract.
